Following Jessica Simpson's Christmas day confirmation of her pregnancy, Weight Watchers has extended their congratulations to the spokeswoman.

"What an amazing year you've had!" the organization Tweeted following the Fashion Star judge's announcement on Tuesday.

Simpson – who lost more than 50 lbs. with Weight Watchers – "will not be following the program during the pregnancy while her weight and well-being are monitored by her obstetrician, as is recommended for any woman during pregnancy," Weight Watchers says in a statement.

The statement adds: "After she gives birth, Jessica and her doctor will decide when she may resume following the Weight Watchers program."

The organization also released a new television advertisement on Wednesday with Simpson sharing the news of her second pregnancy with viewers.

In the spot, the 32-year-old, who gave birth to daughter Maxwell seven months ago, reveals her new body.

"This year is all about new beginnings for me. I lost over 50 pounds on Weight Watchers and did not have to be perfect to do it. Being healthy has become a part of who I am, which is great timing because I'm having another baby," she says. "I feel like I'm on top of the world!"

"We've seen first-hand that Jessica has a refreshed outlook on food, activity and the importance of developing healthy habits, which we hope will guide her through this next pregnancy and beyond," she said. "She has come a long way and we know her story and success will continue to inspire others."
